Bit of a newbie question. Perhaps this is more MIDI than PD anyway

I have managed to sequence an oscilator in PD using MIDI no problem. What I wanted to do is use one PD file to contain all of the elements of a song. The synths/wav files etc.

Then I want to be able to record each of these different elements back into a DAW as separate channels so that I can mix it. Can I do this with noteout ?

Is there an easy way to achieve this ??

By the way I'm using Linux

Thanks

It sounds like all the 'elements' are the sound output of your modules in PD, what you need to do is make as many PD output channels as tracks you want to record in the DAW. Make a multichannel dac object (e.g [dac~ 1 2 3 4 5 6]). Then connect the output of the oscilator, tabplay~, etc into the channels of the dac.

Using your JACK patchbay, (or Patchage) connect the PD outputs to the input tracks of your DAW.

I think I have tried to do it this way but the additional channels don't appear on the Jack Connect panel. Will have another go and try a bit harder this time

I guess from what you are saying is that Jack isn't limited to physical channels on my computer ?

Not sure specifically about Linux, but I image it's similar. On OSX, at least, in Jack's preferences you set the amount of virtual ins and outs. Those will be the number allocated to each application. So if you need six out's on your [dac~], you'll need to have six virtual outs, and you'll need six virtual ins to get them on separate tracks in your DAW.

In Linux the JACK 'system' inputs and outputs are limited to what you physically have on your soundcard, but inputs and outputs of the software that connects to JACK are controlled by said software.

In the preferences in PD you can specify how many input and output channels you want PD to use.These channels will show up in the JACK patchbay under 'puredata'.

The DAW that I use is Ardour, and when you add tracks in the program, those channels show up in the JACK patchbay. Each track will get an input and an output that can be connected to the input or output of another program. In this case you want your outputs from puredata to connect to the inputs of the individual tracks in Ardour.

If you don't see the inputs and outputs from puredata or your DAW in the JACK patchbay then:

1. your software is not connecting to JACK...it's probably connecting directly to ALSA
   or
2. you are starting the software before you start JACK, in which the software isn't getting registered with JACK, and JACK can't manage the connections.

I'll make some screenshots for you if that will help

I've had another go and cracked if I start pd from the command line using

$pd -jack -inchannels 2 -outchannels 8

with jack already running then I get the additional channels I wanted.

I will have a look and see if I can set it up in the preferences.

Thanks All for the help
